This application is a Divisional of U.S. patent application Ser. No. 13/216,462, Filed Aug. 24, 2011, which is a Continuation-In-Part of my patent application Ser. No. 13/209,571, filed on Aug. 15, 2011.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention is to utilize the thermal energy of a natural thermal energy storage body (100) by transmitting the thermal energy to a heat exchange fluid (104) in a heat gaining device (101) installed at the bottom of an open-loop natural thermal energy releasing system with partial fluid return, the heat exchange fluid (104) rising when heated and descending when cooled. Fluid flow is achieved by generating a temperature differential across the heat gaining device using an outwardly expanded arc-shaped fluid chamber (108) on one side of the heat gaining device (101) and by orienting the heat gaining device (101) in an upwardly inclined or vertical direction. The fluid flow may be augmented by the pumping of an auxiliary fluid pump. Upon rising through a pipeline structure (401) to a temperature differentiation body (103) above the thermal energy storage body (100), the heat exchange fluid (104) in the heat gaining device (101) is enabled to release the thermal energy carried by the heat exchange fluid (104) in multiple directions or in a set direction from a fluid inlet/outlet port (4011) of the pipeline structure (401) to the interior of a space limiting and flow direction guiding structure, a part of the heat exchange fluid (104) being returned through the fluid inlet/outlet port (3012) of the pipeline structure (301) for flowing back to the outwardly expanded arc-shaped fluid chamber (108) and heat gaining device (101) outwardly expanded arc-shaped fluid chamber (108) being located in one or more than one turning location of the open-loop flowpath for temporarily storing a part of the heat exchange fluid (104) and moderating the flow speed of the heat exchange fluid (104) to reduce flow damping of the flowpath to the heat exchange fluid (104) as well as to generate a temperature differential across the heat gaining device (101). The open loop flow path may also optionally include an auxiliary heating/cooling device (115), an auxiliary fluid pump (107), a heat exchange fluid temperature sensing device (TS201), an environment temperature sensing device (TS202), and an electric power control unit (ECU200).

(b) Description of the Prior Art

A conventional open-loop temperature equalization device utilizes the thermal energy of a natural thermal energy storage body to transmit thermal energy to an external temperature differentiation body by adopting a heat exchange fluid as a carrier. An open state often exists between the fluid inlet/outlet port (4011) of one pipeline structure (401) and the fluid inlet/outlet port (3012) of another pipeline structure (301). In the absence of a space limiting and flow direction guiding structure for the heat exchange fluid (104), effective fluid flow is difficult to achieve and thermal energy from the heat gaining device (101) may be dispersed rather than effectively transmitted to the external temperature differentiation body.

SUMMARY OF THE INVENTION

The present invention is an open-loop natural thermal energy releasing system with partial reflux installed in a natural thermal energy storage body (100) which is constituted by a solid or liquid heat storage body having a high but stable heat storage capacity, such as a stratum, ground, lake, pool, river, desert, berg for ocean. Thermal energy stored in the natural heat storage body is transmitted to a heat exchange fluid (104) in a heat gaining device (101) installed at the bottom of the open-loop natural thermal energy releasing system with partial reflux, and the cold descending/hot ascending effect provided by the heat exchange fluid (104), after being processed with temperature equalization or the pumping of an auxiliary fluid pump, is employed to transport the heat exchange fluid (104) through piping (301) and (401) to respective fluid inlet/outlet ports (3012) and (4012) outside the natural thermal energy storage body (100) so as to release the thermal energy in all directions or in a set direction, for example to the interior of a space limiting and flow direction guiding structure that guides the heat exchange fluid (104) with thermal energy from the fluid inlet/outlet port (4011) of the pipeline structure (401) and returns a part of the heat exchange fluid (104) to the fluid inlet/outlet port (3012) of the pipeline structure (301) for flowing back to the heat gaining device (101). An outward-expanding arc-shaped fluid chamber (108) is installed at one or more than one of the turning locations of the open-loop flowpath configured by the heat gaining device (101), the pipeline structure (301), the space limiting and flow direction guiding structure, and the pipeline structure (401) for temporarily storing a part of the heat exchange fluid (104) and moderating the flow speed of the heat exchange fluid (104) with thermal energy for reducing the flow damping of the flowpath to the heat exchange fluid (104). Optionally, an auxiliary heating/cooling device (115), an auxiliary fluid pump (107), a heat exchange fluid temperature sensing device (TS201), an environment temperature sensing device (TS202), and an electric power control unit (ECU200) may also be installed in the flowpath.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A conventional open-loop temperature equalization device utilizes the thermal energy of a natural thermal energy storage body to transmit thermal energy to an external temperature differentiation body by adopting a heat exchange fluid flowing through first and second pipeline structures (301) and (401) as a carrier. In situations where a space limiting and flow direction guiding structure of the heat exchange fluid (104) is not provided, an open state is often formed between the fluid inlet/outlet port (4011) of one of the pipeline structures (401) and the fluid inlet/outlet port (3012) of another of the pipeline structures (301), as a result of which thermal energy from the heat gaining device (101) is dispersed.

The present invention utilizes the thermal energy of the natural thermal energy storage body (100), which is transmitted to a heat exchange fluid (104) in a heat gaining device (101) installed at the bottom of the open-loop natural thermal energy releasing system. The heat exchange fluid (104) is caused to flow by the cold descending/hot ascending effect after processing of the fluid by temperature equalization or pumping by an auxiliary fluid pump, the heat exchange fluid (104) in the heat gaining device (101) releasing the thermal energy in multiple directions or in a set direction from a fluid inlet/outlet port (4011) of the pipeline structure (401), for example to the interior of a space limiting and flow direction guiding structure that guides the heat exchange fluid (104) between the fluid inlet/outlet port (4011) of the pipeline structure (401) and a fluid inlet/outlet port (3012) of a pipeline structure (301) for allowing the heat exchange fluid (104) with thermal energy to be released from the fluid inlet/outlet port (4011) of the pipeline structure (401), and to return a part of the heat exchange fluid (104) to the fluid inlet/outlet port (3012) of the pipeline structure (301) for flowing back to the heat gaining device (101). An outward-expanding arc-shaped fluid chamber (108) is installed at one or more turning locations of the open-loop flowpath configured by the heat gaining device (101), the pipeline structure (301), the space limiting and flow direction guiding structure and the pipeline structure (401) for temporarily storing a part of the heat exchange fluid (104) and thereby moderating the flow speed of the heat exchange fluid (104) to reduce flow damping. An auxiliary heating/cooling device (115); auxiliary fluid pump (107); heat exchange fluid temperature sensing device (TS201); environment temperature sensing device (TS202); and electric power control unit (ECU200) may also be installed.

The structural features and functions of the present invention are illustrated through embodiments illustrated in the accompanying drawings, as follows:

FIG. 1 is a schematic structural view showing an outward-expanding arc-shaped fluid chamber (108) installed between a linear pipeline structure (301) and an upward-inclined heat gaining device (101) and pipeline structure (401), according to one embodiment of the present invention.

As shown in FIG. 1, the heat gaining device (101) is installed in a natural thermal energy storage body (100) which is constituted by a solid or liquid thermal energy storage body with a large and stable thermal energy storage capacity, such as a stratum, ground, lake, pool, river, desert, berg and ocean.

The fluid inlet/outlet port (1011) of the heat gaining device (101) leads to the fluid inlet/outlet port (3012) and a protection net and protection cover device (1010) through the pipeline structure (301). Another fluid inlet/outlet port (1012) of the heat gaining device (101) leads to the temperature differentiation body (103) through the fluid inlet/outlet port (4011) of the pipeline structure (401) and another protection net and protection cover device (1010), such that the heat exchange fluid (104) passing through the heat gaining device (101) follows an open-loop flowpath with partial return (reflux) through the pipeline structures (301), (401) and the temperature differentiation body (103) for releasing the thermal energy to the temperature differentiation body (103)j. The heat exchange fluid (104) is made of a gaseous or liquid fluid having heat storage and conduction properties. The temperature differentiation body (103) is a space or structure having certain functions and configured by a gas or solid or liquid, for receiving the thermal energy released by the heat exchange fluid during system operation.

Features and main components of the embodiment of FIG. 1 are as follows:

-   -   Heat gaining device (101) is made of a material having good heat         conductivity, and provided with a flowpath structure jointly         configured by one or more than one flowpath; or structured by a         conduit structure jointly configured by one or more than one         flowpath. The flowpath is a pipe-like structure having a cross         section A-A formed in a round shape or other geometric shapes,         the interior or exterior thereof being optionally installed with         thermal conductive fin sheets having no negative influence on         the flowing fluid and installed in the natural thermal energy         storage body (100) with an upward inclination; two ends of the         flowpath of the heat gaining device (101) respectively having a         respective fluid inlet/outlet port (1011), (1012) for being         respectively connected to one end of the pipeline structure         (301) and one end of the pipeline structure (401) so as to lead         to the temperature differentiation body (103) for forming the         open-loop flowpath. The flowpath inside the heat gaining device         (101) is upward inclined with respect to horizontal, such that         the fluid inlet/outlet port (1011) at a lower position allows         heat exchange fluid (104) having relatively low temperature to         flow in, and the fluid inlet/outlet port (1012) at a higher         position allows the heat exchange fluid (104) having relatively         high temperature to flow out, so as to cooperate with the heat         exchange fluid (104) to generate a hot ascending/cold descending         effect.     -   Pipeline structure (301) is constituted by a fluid pipeline         structure having one or more than one flowpath. The cross         section C-C of pipeline structure (301) has a round or other         geometric shape, the pipeline structure (301) being configured         by one or more than one of the following means: 1) a material         having good heat conductivity; 2) a material having good heat         conductivity, and the exterior of the whole or a part of the         pipeline segment being covered by a heat insulation member         (109); 3) a pipe-like structure or building structural body         having good thermal insulation properties; one end of the         pipeline structure (301) being formed with one or more than one         fluid inlet/outlet ports (3011) for communicating with the fluid         inlet/outlet port (1011) of the heat gaining device (101) having         one or more than one flowpath; and the other end of the pipeline         structure (301) being formed with one or more than one fluid         inlet/outlet ports (3012) which are jointly configured to lead         to a protection net and protection cover device (1010) of the         fluid inlet/outlet port (1010) for transporting the heat         exchange fluid (104).     -   Pipeline structure (401) is constituted by a fluid pipeline         structure having a cross section D-D with a round or other         geometric shape, the pipeline structure (401) being configured         by one or more than one of the following means: 1) a material         having good heat conductivity; 2) a material having good heat         conductivity, and the exterior of the whole or a part of the         pipeline segment being covered by a heat insulation member         (109); 3) a pipe-like structure or building structural body         having good thermal insulation properties; one end of the         pipeline structure (401) being formed with one or more than one         fluid inlet/outlet ports (4012) for communicating with the fluid         inlet/outlet port (1012) of the heat gaining device (101) having         one or more than one flowpath. The other end of the pipeline         structure (401) is formed with one or more than one fluid         inlet/outlet ports (4011) leading to the protection net and         protection cover device (1010) for the fluid inlet/outlet ports         for transporting the heat exchange fluid (104).     -   Outward-expanding arc-shaped fluid chamber (108) is constituted         by an outward-expanding arc-shaped flowpath structure formed at         one or more than one of the turning locations of the open-loop         type flowpath configured by the heat gaining device (101), the         pipeline structure (301), the temperature differentiation body         (103) and the pipeline structure (401), for temporally storing a         part of the heat exchange fluid (104) and moderating the flow         speed of the heat exchange fluid (104) with thermal energy,         thereby reducing the flow damping of the open-loop type flowpath         to the heat exchange fluid (104).

The volume of the fluid stored in the outward-expanding arc-shaped fluid chamber (108) installed close to the fluid inlet/outlet port of the heat gaining device (101) is relatively larger, therefore the total heat capacity is larger, when the heat gaining device (101) introduces thermal energy from the temperature differentiation body which is disposed at the exterior and in contact with the heat gaining device. Although the thermal energy is transmitted towards two sides through the fluid, the fluid at the side where the outward-expanding arc-shaped fluid chamber (108) is installed on the heat gaining device (101) generates a smaller temperature difference, the other side where the outward-expanding arc-shaped fluid chamber (108) is not installed generates a greater temperature difference, thereby forming temperature differentiation at two sides of the inlet/outlet ports of the heat gaining device (101).

The illustrated open-loop natural thermal energy releasing system with therefore includes at least a heat gaining device (101), at least a pipeline structure (301) and at least a pipeline structure (401); wherein the heat gaining device (101), the pipeline structure (301) and the pipeline structure (401) can be integrally formed or assembled by plural components, and the dimensions and shape at each connection location for the assembly is in a gradually-altered shape for forming a smooth transition, which can reduce damping while the fluid is flowing, thereby facilitating flow circulation of the fluid.

FIG. 2 is a schematic structural view showing an embodiment in which the outward-expanding arc-shaped fluid chamber (108) is installed between the linear pipeline structure (301) and a vertical heat gaining device (101) and pipeline structure (401).

As shown in FIG. 2, the heat gaining device (101) is installed in a natural thermal energy storage body (100) which is constituted by a solid or liquid thermal energy storage body having a large, stable thermal energy storage capacity, such as a stratum, ground, lake, pool, river, desert, berg and ocean.

The fluid inlet/outlet port (1011) of the heat gaining device (101) leads to the fluid inlet/outlet port (3012) and a protection net and protection cover device (1010) through the pipeline structure (301), and another fluid inlet/outlet port (1012) of the heat gaining device (101) leads to the temperature differentiation body (103) through the fluid inlet/outlet port (4011) of the pipeline structure (401) and another protection net and protection cover device (1010), such that the heat exchange fluid (104) passing the heat gaining device (101) follows an open-loop flowpath through the pipeline structures (301), (401) and the temperature differentiation body (103) for releasing thermal energy to the temperature differentiation body (103). The heat exchange fluid (104) is made of a gaseous or liquid fluid having heat storage and conduction properties. The temperature differentiation body (103) is a space or structure having certain functions and configured by gas or solid or liquid, for receiving the thermal energy released by the heat exchange fluid during system operation.

Features of main components of this embodiment are as follow:

-   -   Heat gaining device (101) is made of a material having good heat         conductivity, and provided with a flowpath structure jointly         configured by one or more than one flowpath; or structured by a         conduit structure jointly configured by one or more than one         flowpath, wherein the flowpath cross section A-A is a cross         section of a pipe-like structure formed in a round shape or         other geometric shapes, the interior or exterior of the heat         gaining device (101) being optionally installed with thermal         conductive fin sheets having no negative influence on the         flowing fluid and installed vertically in the natural thermal         energy storage body (100). The two ends of the flowpath of the         heat gaining device (101) respectively have a fluid inlet/outlet         port (1011), (1012) for being respectively connected to one end         of the pipeline structure (301) and one end of the pipeline         structure (401), both of which lead to the temperature         differentiation body (103) for forming the open-loop flowpath,         the flowpath inside the heat gaining device (101) being vertical         with respect to the horizontal level, the fluid inlet/outlet         port (1011) being at a lower position to allow heat exchange         fluid (104) having relatively low temperature to flow in, and         the fluid inlet/outlet port (1012) being at a higher position to         allow the heat exchange fluid (104) having relatively high         temperature to flow out, so as to cooperate with the heat         exchange fluid (104) to generate a hot ascending/cold descending         effect.     -   Pipeline structure (301) is constituted by a fluid pipeline         structure having one or more than one flowpath with a cross         section C-C that is round or has other geometric shapes. The         pipeline structure (301) is configured by one or more than one         of the following means: 1) a material having good heat         conductivity; 2) a material having good heat conductivity, and         the exterior of the whole or a part of the pipeline segment         being covered by a heat insulation member (109); 3) a pipe-like         structure or building structural body having good thermal         insulation properties; one end of the pipeline structure (301)         being formed with one or more than one fluid inlet/outlet port         (3011) for communicating with the fluid inlet/outlet port (1011)         of the heat gaining device (101). the other end of the pipeline         structure (301) is formed with one or more than one fluid         inlet/outlet port (3012) jointly configured to lead to the         protection net and protection cover device (1010) for         transporting the heat exchange fluid (104).     -   Pipeline structure (401) is constituted by a fluid pipeline         structure having one or more than one flowpath and a cross         section D-D having round or other geometric shapes. The pipeline         structure (401) is configured by one or more than one of the         following means: 1) a material having good heat conductivity; 2)         a material having good heat conductivity, and the exterior of         the whole or a part of the pipeline segment being covered by a         heat insulation member (109); and/or 3) a pipe-like structure or         building structural body having good thermal insulation         properties. One end of the pipeline structure (401) is formed         with one or more than one fluid inlet/outlet ports (4012) for         communicating with the fluid inlet/outlet port (1012) of the         heat gaining device (101). The other end of the pipeline         structure (401) is formed with one or more than one fluid         inlet/outlet port (4011) leading to a protection net and         protection cover device (1010) for transporting the heat         exchange fluid (104).     -   Outward-expanding arc-shaped fluid chamber (108) is constituted         by an outward-expanding arc-shaped flowpath structure formed at         one or more than one of the turning locations of the open-loop         type flowpath configured by the heat gaining device (101), the         pipeline structure (301), the temperature differentiation body         (103) and the pipeline structure (401), for temporarily storing         a part of the heat exchange fluid (104) and moderating the flow         speed of the heat exchange fluid (104), thereby reducing the         flow damping of the open-loop type flowpath to the heat exchange         fluid (104).

The volume of the fluid stored in the outward-expanding arc-shaped fluid chamber (108) installed close to the fluid inlet/outlet port of the heat gaining device (101) is relatively larger, and therefore the total heat capacity is larger, when the heat gaining device (101) introduces thermal energy from the temperature differentiation body which is disposed at the exterior and in contact with said device. Therefore, even though the thermal energy is transmitted towards two sides through the fluid, the fluid at the side where the outward-expanding arc-shaped fluid chamber (108) is installed on the heat gaining device (101) generates a smaller temperature difference and the other side where the outward-expanding arc-shaped fluid chamber (108) is not installed generates a greater temperature difference, thereby forming temperature differentiation at two sides of the inlet/outlet ports of the heat gaining device (101).

FIG. 3 is a schematic structural view showing an embodiment in which the outward-expanding arc-shaped fluid chamber (108) is installed between an arc-shaped pipeline structure (301) and the upward-inclined heat gaining device (101) and arc-shaped pipeline structure (401).

As shown in FIG. 3, the heat gaining device (101) is installed in a natural thermal energy storage body (100) which is constituted by a solid or liquid thermal energy storage body having a large and stable thermal energy storage capacity, such as a stratum, ground, lake, pool, river, desert, berg and ocean.

The fluid inlet/outlet port (1011) of the heat gaining device (101) leads to the fluid inlet/outlet port (3012) and to a protection net and protection cover device (1010) through the pipeline structure (301). Another fluid inlet/outlet port (1012) of the heat gaining device (101) leads to the temperature differentiation body (103) through the fluid inlet/outlet port (4011) of the pipeline structure (401) and the protection net and protection cover device (1010) for the fluid inlet/outlet port, such that the heat exchange fluid (104) passing the heat gaining device (101) is enabled to follow an open-loop flowpath through the pipeline structures (301), (401) and the temperature differentiation body (103) for releasing the thermal energy to the temperature differentiation body (103). The heat exchange fluid (104) is made of a gaseous or liquid fluid having heat storage and conduction properties. The temperature differentiation body (103) is a space or structure having certain functions and configured by gas or solid or liquid, for receiving the thermal energy released by the heat exchange fluid during the system operation.

Features of main components of the embodiment of FIG. 3 are as follows:

-   -   Heat gaining device (101) is made of a material having good heat         conductivity, and provided with a flowpath structure jointly         configured by one or more than one flowpath; or structured by a         conduit structure jointly configured by one or more than one         flowpath, wherein the flowpath cross section A-A of the         pipe-like structure has a round shape or other geometric shapes.         The interior or exterior of the heat gaining device (101) can be         installed with thermal conductive fin sheets having no negative         influence on the flowing fluid and installed in the natural         thermal energy storage body (100) with an upward inclination.         Two ends of the flowpath of the heat gaining device (101)         respectively have a fluid inlet/outlet port (1011),(1012) for         being respectively connected to one end of the pipeline         structure (301) and one end of the pipeline structure (401) so         as to lead to the temperature differentiation body (103) for         forming the open-loop flowpath. The flowpath inside the heat         gaining device (101) is upward-inclined with respect to the         horizontal level, such that the fluid inlet/outlet port (1011)         at a lower position allows the heat exchange fluid (104) having         a relatively low temperature to flow in, and the fluid         inlet/outlet port (1012) at a higher position allows the heat         exchange fluid (104) having a relatively high temperature to         flow out, so as to cooperate with the heat exchange fluid (104)         to generate a hot ascending/cold descending effect.     -   Pipeline structure (301) is constituted by a fluid pipeline         structure having a cross section C-C having round or other         geometric shapes, the pipeline structure (301) being configured         by one or more than one of the following means: 1) a material         having good heat conductivity; 2) a material having good heat         conductivity, the exterior of the whole or a part of the         pipeline segment being covered by a heat insulation member         (109); and 3) a pipe-like structure or building structural body         having good thermal insulation properties; one end of the         pipeline structure (301) being formed with one or more than one         fluid inlet/outlet port (3011) for communicating with the fluid         inlet/outlet port (1011) of the heat gaining device (101) having         one or more than one flowpath. The other end of the pipeline         structure (301) is formed with one or more than one fluid         inlet/outlet port (3012) which are jointly configured to lead to         the protection net and protection cover device (1010) for each         of the fluid inlet/outlet ports for transporting the heat         exchange fluid (104).     -   Pipeline structure (401) is constituted by a fluid pipeline         structure having one or more than one flowpath with a cross         section D-D having round or other geometric shapes, the pipeline         structure (401) being configured by one or more than one of the         following means: 1) a material having good heat conductivity; 2)         a material having good heat conductivity, the exterior of the         whole or a part of the pipeline segment being covered by a heat         insulation member (109); and 3) a pipe-like structure or         building structural body having good thermal insulation         properties; one end of the pipeline structure (401) being formed         with one or more than one fluid inlet/outlet port (4012) for         communicating with the fluid inlet/outlet port (1012) of the         heat gaining device (101) having one or more than one flowpath.         The other end of the pipeline structure (401) is formed with one         or more than one fluid inlet/outlet port (4011) leading to the         protection net and protection cover device (1010) for each of         the fluid inlet/outlet ports for transporting the heat exchange         fluid (104).     -   Outward-expanding arc-shaped fluid chamber (108) is constituted         by an outward-expanding arc-shaped flowpath structure formed at         one or more than one of the turning locations of the open-loop         type flowpath configured by the heat gaining device (101), the         pipeline structure (301), the temperature differentiation body         (103) and the pipeline structure (401), for temporarily storing         a part of the heat exchange fluid (104) and moderating the flow         speed of the heat exchange fluid (104), thereby reducing the         flow damping of the open-loop type flowpath to the heat exchange         fluid (104);

The volume of the fluid stored in the outward-expanding arc-shaped fluid chamber (108) installed close to the fluid inlet/outlet port of the heat gaining device (101) is relatively larger, and therefore the total heat capacity is larger, when the heat gaining device (101) introduces thermal energy from the temperature differentiation body which is disposed at the exterior and in contact with said device. Although the thermal energy is transmitted towards two sides through the fluid, the fluid at the side where the outward-expanding arc-shaped fluid chamber (108) is installed on the heat gaining device (101) generates a smaller temperature difference while the other side where the outward-expanding arc-shaped fluid chamber (108) is not installed generates a greater temperature difference, thereby forming temperature differentiation at the two inlet/outlet ports on the two sides of the heat gaining device (101).

The above-described open-loop natural thermal energy releasing system includes an open-loop flowpath with partial fluid return configured by at least a heat gaining device (101), a temperature differentiation body (103), at least a pipeline structure (301) and at least a pipeline structure (401), wherein the heat gaining device (101), the pipeline structure (301) and the pipeline structure (401) can be integrally formed or assembled by plural components, and the dimension and shape at each connection location for the assembly is gradually-altered to form a smooth transition, the smooth transition reducing damping while the fluid is flowing, thereby facilitating the flow circulation of the fluid.
